  • a technology of providing a wireless Broadcast Multicast Service using a mobile communication system develops fast, and is increasingly merged with a traditional digital audio broadcast technology, a traditional digital video broadcast technology, etc.
  • MBMS Multimedia Broadcast Multicast Service
  • 3GPP 3rd Generation Partnership Project
  • the MBMS refers to a point-to-multipoint service in which data is sent from one data source to multiple UEs, enabling sharing of core network resources and access network resources, particularly air interface resources.

  • SFN Single Frequency Network
  • a method for determining an SFN area in the prior art includes assigning the size of the SFN area based on Broadcast Multicast Service planning. After a certain time period of operation, the size of the SFN area may be reassigned when the Broadcast Multicast Service region is required to be adjusted. In such a method, the SFN area is constant between two assignment of the SFN area size, and the method is static.
  • the distribution of UEs subscribing for a particular Broadcast Multicast Service may vary dynamically, and thus the UEs may be present at the edges of some SFN area cells, and cannot make full use of the SFN area because such edges are not covered by the macro diversity, resulting in a degraded reception quality.

  • the principle of cell choice is as follows: on the basis of the assumption that the performance of the macro-diversity needs protection, the cell (called as cell-B) without the interested UE should not be carelessly excluded while the cell (called as cell-A) with users interested in the related MBMS service is joined into the final SFN.
  • a simple way on how to select a cell-B and join it into the final SFN is to directly choose these cell-Bs adjacent to the cell-As.

In the case of the "Hole” as shown in Figure 6 , i.e. the case where cells neighboring to the cell determined as "Null" are determined as "Available", the "Hole” cell is required to activate its function of eMBMS transmission.
  • Figure 7 shows the case of an "Isolated island". As shown, if cells neighboring to a cell determined as “Available” are determined as “Null", the activation of the eMBMS transmission function of the cell determined as "Available” alone is insufficient for obtaining a macro diversity gain, and thus the cells neighboring to the cell determined as "Null” are required to activate their function of eMBMS transmission.
